The six gorm.Open calls in the internal/delivery tests passed a bare
gorm.Config, which installs GORM's default logger; they now pass
gormlog.New over a logger that discards, as every production call does,
so the unfiltered form is no longer in the tree to be copied.
The README and the ParamsFilter comment said (*gorm.DB).Scan had one
test-only caller; there are more. Both now say only tests call it, with
fixture data.
